Do people really fall for scam like that?
First, I assume the author knows the email came from github, as the screenshot does not show this very clearly. If that's the case:
Red flag #1: email links to a variation of real domain. If you don't have information on who github-scanner.com is, it is pretty safe to assume it's a scam , just because it sounds like a real website.
GIANT Enormous Huge Red Flag #2: captcha asks you to types command in shell. I have no comment on how naive one must be to do this.
- thephyber 2y agoIt’s a numbers game. Nobody is perfect. The more features of credibility, most likely there will be a higher percentage of conversions. But not everybody has excellent vision, is not time-pressured, and is not tired/exhausted. There are lots of conditions that make otherwise difficult fraud targets more easy to trick. And if it can be done at large scale / automated, then small conversion rates turn into many successful frauds (compromised accounts).
- szundi 2y agoThanks for this summary. People often forget they (hopefully) have grandmas and themselves sometimes making mistakes as well for -- whoever knows what reason. Sometimes.
- generic_dev_47 2y agoAgree, I once fell for a scam that I think I otherwise wouldn't because of string of circumstances: Being tired and stressed, it being Christmas time and I had actually ordered stuff but also because I had just upgraded iOS to the first version that put the address bar in Safari on the bottom of the screen instead of the top so I forgot to check the domain! I've since changed the address bar back to the top… In the end I didn't loose anything but it was a good wakeup call for sure.
- acomjean 2y agoI think they’re hoping for coincidences and the higher the numbers the more likely they’ll find one. I got a real letter from the IRS two days before I got the scam message on my answering machine. The timing was uncanny and I might easily have fallen for it, had I not already dealt with it. It’s the same for the Chinese language calls, if you speak Chinese it really resonates. There was a scam in the 90s where you’d call a number and they’d give you sports betting advice. They’d do it for free as a promotion trying to sell their service when you won. They’d tell half the callers bet team A and the other half team B. The numbers made it work. “Splitting games 50-50 like that—known in the biz as "double-siding"—is the oldest trick in the handicapper's very thick book. That way he knows he has at least some happy customers coming back. “ https://vault.si.com/vault/1991/11/18/1-900-ripoffs-the-ads-for-call-in-services-that-offer-sure-thing-betting-advice-on-the-big-games-couldnt-be-more-tempting-our-own-hot-tip-dont-touch-that-phone https://vault.si.com/vault/1991/11/18/1-900-ripoffs-the-ads-...
- ceejayoz 2y agoEmail from a different domain is unfortunately quite common. Citi and PayPal both do it for some emails. Pisses me off every time.
- szundi 2y agoI just don't get it, how hard it could be? How expensive this could be? Because lots of times they just pay these damages to the customer, because no one knows how this very secure credit card data was compromised. This baffles me. Someone, please enlighten us, there must be a valid reason - at least from an angle.
- sofixa 2y agoHaving a bunch of different domains can serve multiple purposes. In GitHub's case, they already have githubusercontent.com to avoid serving untrusted stuff from their own github.com domain. Sending marketing or security scanner (potentially very spammy) notification emails from separate domains can help with reputation too, to avoid your main domain getting marked as spam. These are all legit; Amex having 20 different of domains, half of which smell like phishing, and still sending emails from other domains is just incompetence. Something like marketing people or someone dealing with strategy deciding to do stuff in a certain way, with nobody technical in the room to tell them why that would be a problem. As an example, a friend of mine's organisation wanted to do a SaaS website for their niche, and a separate website to advertise the SaaS (separate domain, visual identity, everything).
- progval 2y agoMy theory for most of these cases: they would need permission from who knows what department(s) to set up a subdomain of the main domain for their project, and it's easier to just purchase a new domain for the team/project.
- Zopieux 2y agoNailed it. This is 100% pragmatism/convenience-based decision making rooted in terrible culture, red tape, bad communication and dumb org charts.
- mewpmewp2 2y agoI can understand clicking on the link while not paying attention, but I do wonder how many people who are signed up on GitHub would follow through with pasting this command. I could understand if elderly non technical people might follow up with it, but this one, I wonder what the rate is.
- hmottestad 2y agoJust clicking on the link might be enough. Maybe you have a slightly outdated browser with a known vulnerability. Maybe you’re holding off on installing an update just to be sure it won’t break anything. And even if everything is up to date Pwn2Own regularly shows that having a user browse to a website is enough to get root access. Thankfully most people don’t have to worry about this since they are unlikely to attract the attention of someone with that level of resources.
- hmottestad 2y agoIf I had those kinds of resources I might even put a captcha on the site that asks the user to do something incredibly stupid just to make them think they were in the clear.
- mewpmewp2 2y agoYeah, I think the barrier to get people to just click on a link (outside of e-mail as well) is very low, so that would be easy to affect anyone.
- mixtureoftakes 2y agoHonestly i would have typed commands in shell if "captcha" asked me for it. Just to see the scale of outcome's awfulness. I'm almost bored enough to just start installing weird malware for research and funsies
- fijiaarone 2y agoEveryone has been trained for years to do this: curl http://obscure.url?random-string http://obscure.url?random-string | sh
- fijiaarone 2y agoor even this: git clone http://github.com/unknown/repo.git http://github.com/unknown/repo.git && cd repo && npm install
- darkwater 2y agoEven worse: $ svn checkout $ ./configure $ make # make install
- dullcrisp 2y agoIf there were a legitimate looking GitHub how-to page that asked me to do that, I can see myself doing it. Fortunately, I ignore all security issues on my repositories.
- ToValueFunfetti 2y agoSecurity by lack thereof
- kurisufag 2y agopeople make a lot of noise about piping into shell, but even if the instructions were wget random.club/rc-12-release.sh chmod +x ./rc-12-release.sh ./rc-12-release.sh almost nobody would actually read the script before running it
- dullcrisp 2y agoWell yeah, if your intention is to install software from random.club on your system, what would be the point of checking the installer script? The worst thing it can do is the same thing you want it to do.
- lgats 2y agore #1: the email could link to a github pages site hosting the same malware... re #2: it doesn't really have you typing into shell, 'just paste'
- latexr 2y agoA few weeks ago someone opened an issue in one of my repos. In under a minute two accounts replied with links to file lockers asking the user to download and try some software to solve their issue. No doubt it was malware. I promptly deleted the comments and reported the accounts to GitHub. I wouldn’t have fallen for such an obvious ploy, but the original asker seemed like they weren’t particularly technical, judging by the sparse GitHub history and quality of the question. I could see them perhaps falling for that if they were uncritical and too eager to try anything.
- zahlman 2y agoNot only does it ask you to copy and paste a command in shell, but Windows apparently warns you that it will run with admin privileges. Aside from that: > Nowhere in the email does it say that this is a new issue that has been created, which gives the attacker all the power to establish whatever context they want for this message. What about the non-user-controlled "(Issue #1)" in the subject line?
- eviks 2y ago> Red flag #1: email links to a variation of real domain It's too common, MS also does this, to be a red flag
- sureglymop 2y agoJust to let you know, even github themselves use multiple domains instead of just subdomains of github.com (see githubnext.com). So, I wouldn't blame the victims here if the service itself does not realize why that is not such a good idea.
- 8n4vidtmkvmk 2y agoYeah.. I don't like when companies do that. I usually Google the domain first to see if it's legit, but even that isn't foolproof.
- thih9 2y agoIf this was within my first year of owning a GitHub account, I would absolutely fall for this. It's not much different from setting up your ssh key - something that you have to do; and new users also go through this workflow by copy pasting commands that GitHub sends them.
- jampekka 2y agoA prime example how all the paranoid security hoops can easily make things more insecure in aggegate. Since Microsoft embracing and extending it, GitHub has become one of the worst offenders.
- obscurette 2y agoI'm old enough to remember ILOVEYOU. During years after that I have seen millions and millions thrown into educating users not to click on wrong things. Last month I was in conference where the keynote was from CEO of cyber security company. The whole point of the speech was that we need more money because in some cases more than 80% users still fall into email scams. My very serious question to the speaker was - if after many millions and almost 25 years more than 80% users still click on wrong links, then maybe we do something really wrong?
- bugtodiffer 2y agoWe are, but people want convenience. Try to get a company built around Word to use another tech that doesn't requires running unsigned macros from emails... You literally can't, they lough at you for saying things like "don't use Microsoft"

- mnau 2y agoWe are not not doing anything wrong, but we are completely neglecting the attacker side. All our actions are defensive. Look at our physical security. Basically nothing is reasonably protected. 99% of stuff (buildings, locks) can be broken into with tools available in any home depot. The key reason why it doesn't happen that much is because it's possible to find the attacker. Why can any scammed just create a website without any traceability? It wouldn't be foolproof, but it would raise a bar.
- chii 2y ago> Why can any scammed just create a website without any traceability? because jurisdictional challenges. Not to mention that this very same traceability would be abused by some other authoritarian gov't to track down dissidents for example. There's no real way to systematically have good security, if the human element is the weakest link tbh. Securing windows is not a technical problem, but a social and educational one.
- edelbitter 2y agoThey do. Just after seeing instructions to run this, and complying: > curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs https://sh.rustup.rs | sh (Yup, .rs is the ccTLD for the Republic of Serbia, of former SFR Yugoslavia)
- chii 2y ago> captcha asks you to types command in shell. I have no comment on how naive one must be to do this. someone who knows computers (like a programmer) might not fall for it, but people who do not know computers, but is dabbling could easily fall for it. The copied command specifically puts in a "user friendly captcha message" into the end, to overflow the run dialog textbox, so that a user who obeyed the instructions will see something vaguely resembling valid captcha verification: # " ''I am not a robot - reCAPTCHA Verification ID: 93752" Phishing and scams are not about catching out pros, but catching out "normies". It's quite scary that the scammers have put thought and effort into the method of infiltration, because this is "novel" as far as i have heard.
- Stratoscope 2y agoRed flag #3: "Github Security Team" A legitimate GitHub email would never mis-capitalize the company name like that. It would be GitHub, as shown in the footer that the attacker does not control. OTOH, this is a very common mistake. The article alternates between the correct GitHub and the incorrect Github. So it would be easy to not notice that error.
- antimemetics 2y agoYou assume the scammers want everyone to fall for this trick. The reality is different - they leave these huge red flags so that people who aren’t very bright or careful will fall for it. That is the same reason why scammers put spelling mistakes in emails - not because they don’t know how to use spellcheck, but because they want to filter out those who would spot these mistakes. They want to scam careless, gullible, „stupid“ people, not someone who is careful enough to spot security red flags.
- godelski 2y ago> Do people really fall for scam like that? I routinely get people opening issues on my projects asking where the source code is or how to fine tune their models on different data or even how to install pytorch.... There's a lot of people on GitHub that don't know the first thing about coding. There's a lot of people on GitHub that don't know how to use Google... This even includes people with PhDs...
- NeveHanter 2y agoI've also seen an issue on GitHub asking project author to add an entry in README.md with instructions on how to clone the repository...
- tom_ 2y agoActually worth doing if the repo uses submodules.
- godelski 2y agohttps://lmgtfy.click/?q=How%20do%20I%20clone%20a%20repository%20with%20submodules%3F https://lmgtfy.click/?q=How%20do%20I%20clone%20a%20repositor...
- keybored 2y agoThe naive way in this case wouldn’t be to make an issue: How do I clone this repo? I see it has submodules The naive way would be to just clone the repo without any (apparently) options. I can attest to this because that’s probably what I would do. The readme would not resolve a problem that someone knowingly had. It would resolve an unknown upcoming problem.
- tom_ 2y agoYeah, git clone --recursive is the main thing I suggest. But unlike Google I include the exact command that you can copy and paste into the terminal to clone the specific repo in question. And if you're reading the README after cloning it already, there are instructions for sorting that out too, also suitable for copy and paste. Or if you downloadeded the ZIP from GitHub - I'm sorry. But you won't be left too confused, at least you won't if you read my README, because my README covers this situation as well. (Also: don't forget to git submodule update after changing branch! But if you're noting everything my README tells you, you won't.)
- prmoustache 2y ago> GIANT Enormous Huge Red Flag #2: captcha asks you to types command in shell. I have no comment on how naive one must be to do this. I guess critical thinking of devs and wannabee devs has been softened by all the `curl <script> | bash` installation instructions.
- d3nj4l 2y agoYeah exactly, I do that all the time when filling captcha!
- Dibby053 2y ago>GIANT Enormous Huge Red Flag #2: captcha asks you to types command in shell. I have no comment on how naive one must be to do this. Funnily enough there's at least one legit captcha that has you do this: if you have JavaScript/WASM disabled it gives you the option of running the anti-DDOS proof-of-work in a shell and pasting the result in a textbox.
- maicro 2y agoAll valid points, but I will say services don't help in this situation - I received an email from @redditmail.com recently, which is real and part of reddit but feels off on first glance. Couple that with gmail having no way to show the full email address (by default - I know you can hover, etc.), rather than the sender-provided "sender name", and my false-positive rate for at least double checking and confirming the sending domain is kinda high...better that than a bunch of false-negatives of course.
- voytec 2y ago> Do people really fall for scam like that? Yes. It wouldn't be a thing otherwise. I know at least two fairly intelligent people, one literally being a Mensa member, who fell for sextortion emails and got their files encrypted. Scareware is based on social engineering, and is crafted to trigger emotional response, not educated one.
- me-vs-cat 2y ago> Do people really fall for scam like that? You should put a "voice activated" sticker on a random break room appliance (toaster, water/ice dispenser, microwave, coffee machine, ...). Don't use strong adhesive if your desk is within hearing distance.
